Sope throw checksum errors on the disk, so that a standard cd player won't notice (doesnt check, time is more important than accuracy), but cd-roms, which verify data read (accuracy is more important than time) fail. hmmm ... I am not very familiar with copy protection methods used on audio CD's, but anyway this can be hardly true, because ... audio data are written without CRC, and even without sector headers i.e one audio sector = 2352 bytes, and therefore jitter efect is very common on lot of CD drives (different data are received, if ripping the same song twice) sector for data has 2048 bytes for data + 304 bytes for CRC and header Radiohead's 'hail to the theif' cd works like this. I can play some of it using xmms' cdread plugin, but I end up having to revert to analog cd playing to actually listen to the disc. Now, one possible way to rip it is to not use the digital ripping of the disc, instead recording the cd-audio channel while playing (shouldnt be affected by volume settings methinks). Also, ripping the cd (probably at a low speed) without error checking and then have a nice, proper .iso. You could burn this for future cd use, or you could see if grip can rip from an .iso image. -- [EMAIL PROTECTED] mailing list
[gentoo-user] CD's and MP3's

Any comments welcome regards Paul Hello, merry xmas to you too. I have a couple of copy-protected audio CDs, which I've not been able to rip using Linux (tried CDDA2WAV paranoia on two different, quite new, drives). But I've successfully ripped them in WinXP without doing anything special (my laptop declares war everytime I try to install Linux on it). I used Easy CD Creator, which just ignored all copy protection on the CDs and ripped them happily to proper WAV files (not talking about the WMA crap included on many of these CDs). This may be because of a different drive, but may also be software related, I don't know. I try to avoid all CD products that are sold in a damaged state. Try different drives or try to rip them on an XP install, if that's possible for you.

Re: [gentoo-user] CD's and MP3's
i have never had any problems ripping those cd's, but i found a way to do it on a friends machine ;D dd if=/dev/cdrom of=musiccd.iso then you have the image of the cd, and then create entry in fstab, and use the cdrom plugin for xmms and point to the iso mount point, and then use the xmms wavout plugin to write wav files, and then use lame or oggenc, and you are set ;D On Wed, 2003-12-24 at 11:34, Paul Stear wrote: Hi all, A very merry xmas to all.
